Information : Powder Coating of Support Equipment Components
Letterkenny Army Depot (LEAD) has the ability to powder coat small and medium sized parts with simple shapes (such as brackets, frames, boxes, and panel fronts) which are later assembled into equipment racks and control panels. The process is listed as an alternative to the liquid epoxy painting system used extensively within the Department of Army.
The use of powder coating improves the quality and finish of the item while extending service life. The current liquid coatings force the use of solvents and primers which increase hazardous emissions and waste of the liquid application. Table 3-1 shows the significant difference in the costs associated with liquid versus powder applications.
Additionally, the powder not attached to the item can be recovered from the filters and reintroduced into the application media. Cure times are substantially reduced with powder versus liquid application, and powder coatings have no vapor off-gassing issues.
For years, the use of powder coatings has been a proven performer in numerous applications. Once customer approval for this process is secured, it will enhance LEAD’s ability to provide a significantly improved product.
